US. Patent Nov. 18, 1975 Sheet 2 of 2 FLEXIBLESTRAP HANGER cxGRoUNo'oi- THE INVENTION I This invention relates to a strap hanger particularly useful for hanging large objectsjsuch as sidesof beef or other fresh meats .on the existing overhead-beams of meat carriers such as, truck trailers.

Presently, most meats, such as beef sides, are hung in trucks and the like on S-like steel hooks which are heavy and expensive, adding to the cost of transportatiomQne end of these hooksis stuck intozthe meat and the other end is slung over the overhead beams in the truck to suspend the meat during transit.

Attempts to replace steel hookswithstraps of woven or non-woven construction or plastic materials have met with resistance due to the necessity. of installing conversion hooksl in the trucks. Such hardware isre quiredto accornodate the hanging of straps from the existing overhead rails; These adaptors areexpensive, difficult and costly to install and restrict the usable cargo area of the vehicle. Vehicles so adapted, moreover, can no longer readily be utilized incarrying; fresh meats suspended by the conventional steel hook system. )ther,objections "encountered include, strength loss oficertain materials when subjectedto extreme cold temperatures; undesirable elongation characteristics causing possible. contact of the meat with the floor ofthe vehicles; and possibilities strap breakage .due to impalin'g of the! strap whe'ns'uspenrled' from the abovefrnetitibned conversion hooks. l i

In a presently preferred embodiment, there is provided a strap hanger for hanging fresh meats such as sides of beef, comprising a flat webbing woven from polyester yarn, said webbing having a thickness from l/32 to 3/16 inch and a width ranging from A to 2 inches and being folded over on itself and stitched or mechanically fastened at both ends to form substantially identical loops at each of said ends, said loops having a length between 3 and inches; a sliding bar in the form of an elongated rod ofa length at least three times the width of said webbing but not exceeding four times the width of said web and a diameter ranging from %'to 1' inch;.said sliding bar having a slot extending along the axis thereof; said slot having a length exceeding the webbing width-by 1/32 to. 4; inch and a height approximately equal tothe webbing thickness; said webbing extending through said slot whereby said sliding bar is constrained from sliding off either. end of said strap, whereby one end of said strap can be forced througha piece of meat, the second end is fed through the loop in said one end, draped over an overhead beam, loopedaround both ends of said sliding bar and secured to said overhead beam by sliding said bar upwardly along said webbing.

v DETAILED DESCRIPTION FIG. 1 is a perspective view of the strap hanger of the invention. 1i FIGSZ and'3 are views showing the lower portion of thestrap hanger being secured to a beef side.

FIG. 4is aperspective view showing a beef sidesuspended from an overhead beam using the strap hanger ofthe invention.

*The strap hanger ll of this invention comprises a strapping 12, preferably a webbing woven frorn' polyethylene terephthalate polyester continuous multifilam'ent fiber'having a denier from 500 to 1300 in the warp direction, zero twistfand a strength of at least 8 grams per denier, preferably at least 8.3 grams per deni'er. This fiber has the characteristics of havin g high strength, low elongation under load, high impact strength at low temperatures, and being safe for" food contact uses.

a The strapping 12 is preferably flat having a width of to2inches, preferably to inch and a thickness of'about"l/32 to 3/16 inch," preferably l/32 to inch. Webbing'woven to this width and thickness using the yarn specified above provides strapping which can be threaded through beef sides and handled without excess twisting,'but not so bulky and stiff as to make the strapping hard to handle when manipulating loop 13 onto fastener bar 14. I

The loop 'l3is formed by folding the webbing over on itself and stitching same or mechanically fastening in place to provide adequate joint strength, preferably at least'60% of the tensile strength of the strap, so that substantially'identical'loop 13 is formed at each end of the st'rappi ngl2 The loop 13 has a length L"ranging from 3 to 10 inches. Smaller loops are difficult to secure to fastener bar 14, and larger loops'will not allow the fastener bar to slide far enough up the webbing to securely cinch it to 'the overhead beam found in most carriers.

A sliding bar fastener 14 having a slot 15 therein is provided to slide along the strapping l2 and act as a fastener for the loop 13 slung over beam 16 in a carrier. This bar 14 preferably takes the form of an elongated cylindrical rod of a length at least three times the width of the strapping l2 and not exceeding four times the width of strapping 12. If the bar 14 is too short, the ends 18 thereof will not provide sufficient surface to adequately secure the loop 13. If the bar 14 is too long, the worker will have trouble securing the upper loop 13 about it. The optimum length of 3-4 times the strapping width provides adequate surface to ensure that loop 13 is properly secured as shown in FIG. 4.

Slot 15 has a length exceeding the webbing width by l/32 to rt; inch and a height of less than twice the strapping thickness, preferably approximately equal to but slightly less than the webbing thickness. Slot 15 is rectangular in form and extends axially and radially'in substantially the middle of the bar 14. The slot location specified assures that the bar ends 18 extend beyond the strapping edges by an equal distance; the slot height of less than twice the strapping thickness assures that the bar will not slip off the strap because it will stop when it strikes the double thickness portion 19 of the strapping doubled back on itself. Most preferably, the slot height is approximately equal to but slightly less than the uncompressed web thickness whereby the friction between the slot 15 and strapping 12 is sufficient to preclude the bar 14 from sliding down the strapping 12 by gravity alone so that the bar will remain in place along the length of the strap until moved by a worker or the force of the beef 21 pulling upwardly on the strap to secure it to beam 16 as in FIG. 4. The bar 14 can be formed from a suitable strong material such as wood, metal, or plastic and is from a diameter ranging from "/3 to 1 inch.

In practice, an article, such as a side of beef 21 to be suspended, is pierced by a piercing tool commercially available, and the strapping 12 is threaded through the meat and then through the opposite loop 13 as shown in FIGS. 2 and 3 and with bar 14 positioned on the upper end of the strapping 12. The strap hanger 11 is secured to the overhead beam 16 by draping the free end of the strapping 12 over the beam 16 (P10. 4) and securing the free loop 13 about the ends 18 of fastener bar 14. The meat is then lowered and the weight of same on the strap causes the loop 13 to pull upwardly on bar 14 causing strapping 12 to cinch up against the beam 16. ln this manner, the beef is secured against falling to the floor or from any sliding movement horizontally due to quick stops, etc. occasioned in transit.

To release the strap hanger 11, the meat is lifted slightly and upper loop 13 is quickly released by hand from around the fastener bar 14 so that the meat 21 can be removed.
